Abstract
A method of making an article includes forming a molten material by melting at least a portion of a mass of a metal and an alloy. The method further includes forming the article by solidifying at least a portion of the molten material within a mold, and contacting the article with plasma during formation of the article. A method for making an article also is disclosed wherein a molten material is formed by melting at least a portion of a mass of one of a metal and an alloy, the molten material is collected within a mold, and at least a portion of the molten material is magnetohydrodynamically stirred within the mold.
Claims18
A method of making an article, the method comprising:
- forming a molten material by melting at least a portion of a mass of one of a metal and an alloy;
- forming the article by solidifying at least a portion of the molten material within a mold;
- and
- contacting the article emerging from the mold with a plasma, wherein the plasma has a temperature that is less than a melting temperature of the article.
An apparatus for melting and casting metals and/or alloys, the apparatus, comprising:
- a melting device including an outlet;
- a molten material mold in fluid communication with the outlet of the melting device;
- and
- a plasma generator positioned adjacent the mold and adapted to direct plasma against an object emerging from the mold, wherein the object is cast in the mold from the molten material.
A method of making an article, the method comprising:
- forming a molten material by melting at least a portion of a mass of one of a metal and an alloy;
- forming the article by solidifying at least a portion of the molten material within a mold;
- and
- transferring heat from the article by contacting the article emerging from the mold with a plasma.
